British Columbia Highway 3B

Highway 3B is an alternate loop to the Crowsnest Highway between Nancy Greene Lake and an area called Meadows, just west of Erie on the Crowsnest. Originally, Highway 3B went between Nancy Greene Lake to Trail, where the Crowsnest picked up the route to the Meadows area. One of its original component sections, the Rossland and Nancy Greene Lake was opened on the 1st of October 1965 at a cost of $3.5 million
Originally, Highway 3B only went between Nancy Greene Lake and Trail, where the Crowsnest picked up the route to the Meadows area. However, in 1978, Highway 3 was re-routed off the present-day Highway 3B alignment east of Trail because a new segment of Highway 3 between Castlegar and Meadows was opened.
